Can't restore data from backup (version 1.6.3)

Hello, I have OpenMRS version 1.6.3, the system crashed and i tried to restore from the backup file. after re-installing the system, i run the restore script and select the backup file. when i run the system, it brings this error;

org.hibernate.exception.SQLGrammarException: could not load an entity: [org.openmrs.Role#Anonymous]

Please help. What can i do to solve this?

@mathiasbbaale are you installing the same version of OpenMRS modules and system that you had before?
